My i.MX28 custom board is powered from linear regulators, VDD5V source only system..


I edit spl_power_init.c in u-boot, but it does not work, just repeats booting fail and restarting .


HW_POWER registers are below now.


v5ctrl  (2403F592),

dcdc4p2 (A080001F),

vddd    (00F00710),

vdda    (000F070C),

vddio   (00070406)


Is there mistakes on setting registers or additional to do?


Best regarts.
